Description

The RN22 is a 1- or 2-channel active barrier, power supply or signal doubler for safe isolation of 4 to 20 mA standard signal circuits. It supplies safely analog measuring loops and safety-related systems up to SIL 2, SC 3 (according to IEC 61508). The transparent HART® interface device provides a reliable signal connection between field devices and the HER process control system. It offers an interface to 2 or 4-wire devices in hazardous areas of zone 2 and provides a second, galvanically isolated signal output according to NAMUR NE 175. This opens a second channel for process optimization without affecting the traditional automation system.

Characteristics

Active barrier for secure isolation of standard signal circuits
Compact casing
Quick and easy wiring
Intrinsic safety for operation in hazardous areas (zone 2)
For safety-related applications up to SIL 2 (SC 3) according to IEC61508 (optional)
